Today, Paulo Zanoni help me to put in a shape the VgaArbiter wiki page.
The primary intention of that page is to bring more developers in that
project and some users++ who could also help testing. Feedback is very
welcome. Here is the link.

Neat but you don’t say what “RAC” is, it’s not on X.org, and wikipedia doesn’t know. “Resource Access Control”? Please link it to something.
hmm, sorry :) The Resource Access Control (RAC) inside Xorg is the guy responsible to take care of the various resources of memory and to share them in a wise manner when two or more graphics devices are active. Cheers.
i am gonna show this to my friend, brother
